Create a zero-filled ndarray having the same shape and data type as a provided ndarray.

Usage

var zerosLike = require( '@stdlib/ndarray-zeros-like' );

zerosLike( x[, options] )

Creates a zero-filled ndarray having the same shape and data type as a provided ndarray.

var zeros = require( '@stdlib/ndarray-zeros' );

var x = zeros( [ 2, 2 ] );
// returns <ndarray>

var y = zerosLike( x );
// returns <ndarray>

var sh = y.shape;
// returns [ 2, 2 ]

var dt = y.dtype;
// returns 'float64'

The function supports the following options:

  • dtype: output ndarray data type. Overrides the input ndarray's inferred data type.
  • shape: output ndarray shape. Overrides the input ndarray's inferred shape.
  • order: specifies whether the output ndarray should be 'row-major' (C-style) or 'column-major' (Fortran-style). Overrides the input ndarray's inferred order.

To override either the dtype, shape, or order, specify the corresponding option. For example, to override the inferred data type,

var zeros = require( '@stdlib/ndarray-zeros' );

var x = zeros( [ 2, 2 ] );
// returns <ndarray>

var dt = x.dtype;
// returns 'float64'

var y = zerosLike( x, {
    'dtype': 'int32'
});
// returns <ndarray>

var sh = y.shape;
// returns [ 2, 2 ]

dt = y.dtype;
// returns 'int32'

Examples

var dtypes = require( '@stdlib/ndarray-dtypes' );
var zeros = require( '@stdlib/ndarray-zeros' );
var zerosLike = require( '@stdlib/ndarray-zeros-like' );

// Get a list of data types:
var dt = dtypes();

// Generate zero-filled arrays...
var x;
var y;
var i;
for ( i = 0; i < dt.length; i++ ) {
    x = zeros( [ 2, 2 ], {
        'dtype': dt[ i ]
    });
    y = zerosLike( x );
    console.log( y.data );
}
